Abstract (en)
[origin: EP1347446A2] In an image recording apparatus for recording an image by guiding zeroth order diffracted light beams from a plurality of diffraction grating type light modulator elements as signal beams to a recording medium, a transition of each of light modulator elements from an OFF state to an ON state is detected and when this transition is detected, the light modulator element is temporarily supplied with an auxiliary driving voltage (V3) between a driving voltage (V1) for bringing the light modulator element into the ON state and a driving voltage (V2) for bringing the light modulator element into the OFF state. This suppresses an overshoot due to a sharp change of the light modulator element to the ON state and achieves beam writing with appropriate line space ratio. <IMAGE>
